Should your state government increase funding to expand local air quality monitoring networks?
Following hazardous air quality levels caused by wildfire smoke in July 2026, Wisconsin officials have announced plans to expand the state's air monitoring network. This initiative aims to better track pollution levels to help residents stay informed about environmental health risks.
Why it matters
Expanding monitoring allows for more precise air quality alerts, which is critical for the thousands of Wisconsin residents who face increased risks for severe asthma attacks during poor air quality events.
Official state health reports show that asthma-related emergency visits hit 2,000 in July 2026, exceeding the 2021-2025 July average of 1,600. The expansion is being designed to address gaps in coverage identified following wildfire smoke events in 2025 and 2026.
The players
Wisconsin State Air Management Program
The state agency responsible for monitoring environmental pollutants and maintaining regional air quality standards.
The details
The state air management program is currently analyzing existing network gaps in Northern Wisconsin and other regions to determine where additional monitors are most needed. These sensors work by measuring concentrations of particulate matter in real-time, providing the data necessary to update the Air Quality Index (AQI) for local communities. Officials are now evaluating the practical deployment of these technologies to ensure coverage reflects the actual conditions experienced during wildfire smoke events.
Timeline
2021-2025: Average July asthma emergency visits totaled 1,600.
2025: Northern Wisconsin experienced significant wildfire smoke events.
July 2026: The state recorded 2,000 asthma-related emergency visits during hazardous air quality.
Health Landscape
This initiative follows the benchmarks established by the National Weather Service's Air Quality Index thresholds to classify pollution risk. It marks a shift toward localized monitoring as climate-related wildfire smoke increasingly complicates the management of respiratory conditions.
If you have asthma, monitor the Air Quality Index in your area during smoky conditions and discuss a personalized action plan with your doctor. Staying indoors and using high-quality air filtration can help minimize exposure when air quality reaches unhealthy levels.
The takeaway
Wildfire smoke can significantly increase the risk of asthma complications, making local air quality data an essential tool for patient safety. Residents should track air quality alerts regularly and consult a physician about adjusting their asthma management plan during periods of poor air quality.
